Windows 8's use of the UEFI Secure Boot

I heard about the UEFI Secure Boot feature that might impair installing
an alternate OS (Linux) or prevent the use of Dual Boot. Supposedly it
would be a part of the motherboard hardware and prevent ANY changes to
the boot sector. Supposedly it would prevent root-kits as there would
be no way to get around it. Has anybody heard more about this and what
would the Ubuntu community do about this?
